AnnouncementApr 3, 2023

Official Flutter SDK release

Customer.io released an official Flutter SDK with support for in-app messaging, rich push notifications with images and links, and event sending from user devices. The SDK will receive ongoing updates alongside OS releases and new Customer.io features.

Our Flutter SDK supports all the same features as our other SDKs, including in-app messaging, support for images and links (rich push), and the ability to send events from your audience’s devices. As an officially-supported SDK, we’ll continue updating our Flutter library to support both OS updates and new features that we expose in Customer.io.
